I'm thinking about fuel pumps.... hmmmmm
Here's the deal. I've go t a '90 4Runner that may have a bad fuel pump. While looking for info on the net I read that the first get 4Runner had a hatch under the rear seats to get to the pump without droping the tank.I replaced the pump in my RX-7 and it was done the same way. I replaced it with a supra TT pump, the old one was still fine.
Now then on my '90 is there a door? If not then what about making one?? would it be possible to get som tin snips in there and make a hatch the cover it with some sheet metal or the like??? Would this be dangerous or even possible? I'm also wondering if the old RX7 fuel pump would be able to replace the Runner pump. The supra is a direct bolt in (same pickup and all) so I'm also wondering if the RX7's pump would be usable in this situation?????
